Have you been postponing your entrepreneurial venture just because you couldn't find a 'niche'? The authors give a variety of examples where some of the great companies didn't start with just one particular idea or product. They tried a number of things before they found their 'magic formula' for success.
The style and the tone of this book resembles "Good to Great". If I had to compare this book with "Good to Great", I'm honest that "Good to Great" was very valuable.
If you really wanted to know the strengths of the companies that are "Built to last", you should read this book.
